In those years, Benedict XVI established "three monuments of unrivalled value: the Congregation for the Oriental Church, later renamed ‘for the Oriental Churches’; the Papal Oriental Institute for the study of the theological, liturgical, juridical and cultural aspects that compose the knowledge of the Christian East; and the ‘Codex Iuris Canonici’". These initiatives benefited the Oriental Catholic Churches, commented the Pope, "which enjoyed a regime that was more befitting their traditions, under the glance of the Roman Pontiffs who never stopped expressing their care, through gestures of factual support". Benedict XVI then mentioned the Library of that Institute, founded by Pius XI, "rightly renowned all over the world, and one of the best about the Christian East". "I am committed ensured the Holy Father to making it grow further, as a token of the interest of the Roman Church in the knowledge of the Christian East and as a means to remove any prejudice that might be detrimental to the friendly and harmonious cohabitation of the Christians". "I actually believe he concluded that support to study has also an effective ecumenical value, since drawing on the heritage of the wisdom of the Christian East enriches everyone".
